"Die Mappe (The Folder or The Portfolio) a German painter and sign painter magazine, published by Verlag George D.W. Callwey, Munich, was aimed at house and office painters, wallpaper hangers and sign designers. The covers, designed in a mid-century modern style (and mostly anonymous) are as contemporary looking today as they were in 1959-1960."
